The System 2000 Auto-Traverse chair is used for testing and monitoring patients with peripheral vestibular loss, dizziness, CTE, TBI, blast injury, otolith dysfunction, vertigo, acoustic neuroma, chronic imbalance, eye tracking abnormalities and other vestibular disorders or brain injuries. A stepper motor shifts the chair left or right to place one ear off-axis during constant velocity rotation for otolith function testing using the subjective visual vertical laser.

Children who are candidates for cochlear implants or those who have balance or motor developmental issues can be tested in this chair by adding the pediatric option. This includes a child seat, pediatric monocular goggles and chair mounted nystagmus observation camera. Patients who are not candidates for caloric tests or those who need to be followed to document vestibular compensation are appropriate for the System 2000 rotational chair.
